Answer:
The Camera will drop in 5 seconds
Step-by-step explanation:
1. y=-16t²+400
2. add -16t² to both sides
3. -16t²=-400
4. divide both sides by 16
5. t²=-25
6. t=√25
7. t=5
The perimeter would just be the equation that they provided to you multiplied by 3 because a triangle has 3 sides, and it is an equilateral triangle, so every side is the same. You do the distributive property to solve the equation and get your final answer.
In the equation (because an expression does not have a equal sign), the x is called the variable, as it can vary (changes value).

Answer:False
Step-by-step explanation:
The center is 3, -1 and the radius is 2 I believe.
Since the formula is (x-h) ^2 + (y-k) ^2 = r^2, the radius here is already squared so 2 would be the radius. The center would be the h and k and since the k is positive, that means it's negative as the sign has been flipped.
Hope this helps!
